If it's for an electropneumatic or blowback, boomstick. If it's for a cocker, as much as I hate them, then I'd go freak, simply because you really do need a kit when using a cocker. But I'd recommend an evil pipe or cp pro kit before I would a freak.
blowback: you should be concentrating on getting a new gun, not on accessories which youll just have to buy a new back for soon.
Closed bolt: get the freak or a different barrel kit(i personally like the empire 7-pieces) since the paint size to bore size match is more important.
Open bolt: get the boomstick(get an ultralite instead since boomsticks are hella heavy). Since on closed bolt markers the paint to bore match only really effects the efficency.
